A252 GR2 LSAW Pipe

 

We are the largest A252 Gr2 pipe expert in Europe and Asia

ASTM A252 Gr2 pipes are pipe piles used for piling. A252 Grade 2 welded pipes are manufactured through longitudinal submerged arc welding or other welding methods. The minimum yield strength of ASTM A252 Grade 2 steel pipes is 240 MPa, and the minimum tensile strength is 415 MPa. GNEE Group, as a professional steel pipe manufacturer, produces A252 GR2 pipe piles with lengths up to 70 metres, wall thicknesses ranging from 5 mm to 30 mm, and outer diameters from 219.1 mm to 3048 mm. GNEE Group also offers a variety of different steel pipe coatings for you to choose from, such as fusion-bonded epoxy coating and 3PE coating. For more information, please feel free to contact us.

A252 GR2 LSAW Welded Pipe Test

A252 GR2 longitudinal welded steel pipes need to undergo mechanical performance tests, flattening tests, and flaring tests to ensure they meet the standard requirements. The steel pipes should be able to withstand a certain internal pressure, and if necessary, a pressure test of 2.5 MPa should be conducted and maintained for 1 minute without any leakage. An eddy current testing method can replace the hydraulic test, and it should be conducted according to the steel pipe eddy current flaw detection standards. The eddy current flaw detection method involves fixing the probe on a frame to maintain a distance of 3-5 mm between the probe and the weld seam, allowing for rapid scanning of the entire weld seam. The eddy current flaw detector automatically processes and classifies the detection signals to achieve the purpose of flaw detection. After flaw detection, the A252 GR2 welded pipes are cut to the specified length using a flying saw and are taken offline via a turnover frame. Both ends of the steel pipes should be plain end beveled and marked. Before leaving the factory, the finished pipes should be bundled into hexagonal shapes and packed.
